A critical point for bifurcation cascades and featureless turbulence

open access: yes, 2019
In this Letter we show that a bifurcation cascade and fully sustained turbulence can share the phase space of a fluid flow system, resulting in the presence of competing stable attractors.

On the use of mode shape curvatures for damage localization under varying environmental conditions

open access: yes, 2018
A novel damage localization method is introduced in this study, which exploits mode shape curvatures as damage features, while accounting for operational variability.

On submanifolds whose tubular hypersurfaces have constant mean curvatures [PDF]

open access: yes, 2011
Motivated by the theory of isoparametric hypersurfaces, we study submanifolds whose tubular hypersurfaces have some constant "higher order mean curvatures". Here a $k$-th order mean curvature $Q_k$ ($k\geq1$) of a hypersurface $M^n$ is defined as the $k$-

Controlling Gaussian and mean curvatures at microscale by sublimation and condensation of smectic liquid crystals [PDF]

open access: yesNature Communications, 2015
Soft materials with layered structure such as membranes, block copolymers and smectics exhibit intriguing morphologies with nontrivial curvatures. Here, we report restructuring the Gaussian and mean curvatures of smectic A films with free surface in the ...

Potential Early Risk Biomarkers for Reduced Forced Expiratory Volume in Children Post‐Hematopoietic Cell Transplantation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT We sought to identify potential early risk biomarkers for lung disease in children post‐allogeneic HCT. Patients with pulmonary function tests 3 months post‐transplant and plasma samples between days 7 and 14 post‐HCT were included. Six of 27 subjects enrolled had reduced forced expiratory volume 1 (FEV1) z scores.

Extrinsic curvatures of distributions of arbitrary codimension

open access: yes, 2010
In this article, using the generalized Newton transformation, we define higher order mean curvatures of distributions of arbitrary codimension and we show that they agree with the ones from Brito and Naveira (Ann. Global Anal. Geom.

Curvatures of hypersurfaces

open access: yesLietuvos Matematikos Rinkinys, 2010
In this article we generalize some classical formulas for curvatures of hypersurfaces in the n-dimensional Euclidean space using the homogeneous formulas.

Nonnegative Curvature on Piecewise Constant Curvature Spaces [PDF]

open access: yesTransactions of the American Mathematical Society, 1992
We consider piecewise flat and piecewise spherical spaces. We prove that every piecewise flat cobordism which is a product near the boundary and has nonnegative curvature must be trivial in the metric sense. We also obtain several restrictions for piecewise p p -spherical manifolds with nonnegative curvature and diameter equal to
